ing on the vigor of the plant. This sudden inversion of the inner
peridium is evidently a mechanical process. I do not exactly understand
it, but think it is due to the thinning of the upper walls of
the inner peridium ,and a contraction at the opening. After the, ejection
of the peridiole the inner peridium, which is thin and white, soon
dries up and disappears, hence is not seen on dried specimens.

the peridioles.
We think our photographs of the plant at the various stages
will make the subject plain. They are all magnified six diameters, as
the plant is not much larger than a mustard seed." In our last figure
(247) two plants are shown that have just thrown out the peridioles.
DU RAND'S PAPER ON GEOGLOSSACEAE.
What impresses me as being a most thorough paper on the Geoglossums
and allied plants of North America appeared in a German
periodical recently. We have all known that Professor Durand has
been at work on the Discomycetes for a number of years, and this
is the first important result of the work. We trust he will publish
the remainder of the field in the same exhaustive manner. Professor
Durand has studied the American specimens of all the principal mu-
seums, both American and European, as well as field work.
having done much
We now have a knowledge of what species occur with
us, where they occur, and their relative frequency or rarity, some-
that it is not
thing that we did not have before. We are only sorry
in a more accessible form, for there are many collectors in America
